When the forks with the external main springs were introduced on the later 1927 models, the straight rockers were used. The bent rockers were used on the Henderson when the front brake and modern tires were introduced. They were then carried over to the Super Xs. There were a number of changes when the forks with external springs were introduced in the later ’27 model.
